We investigate the electron-mediated interaction between atoms adsorbed on the surface of monolayer graphene. The interaction is shown to favour ordered states, whose order parameter depends on the subgroup of the lattice symmetry group preserved by an individual impurity. The corresponding order-disorder phase transitions are studied numerically and the corresponding critical temperatures are calculated. The signatures of the phase transitions in transport and optical properties of the system are discussed
